METHOD FOR DETECTING CHEMICAL SPECIES AND DEVICE FOR IMPLEMENTING SAME

摘要

The present invention relates to a procedure for detection of chemical species as well as the device which carries out said procedure where by chemical species are to be considered those species formed either by molecules or by more complex compounds with sizes which can reach submicrometer scales. This procedure is characterized in the use of a sequential set of stages which allows different classification criteria to be applied to allow the presence or not of target species to be discerned with an almost negligible failure rate. The device which implements these stages applies each discrimination criterion making use of modules capable of distinguishing two species according to a different physical, electrical or chemical property.
